There should be 12v coming from the yellow wire and 5v from red. Open PC and use a multimeter to check the voltage output connect negative probe to the power supply casing and the positive to the red and yellow wires from the molex connectors. If the readings are below the mentioned voltages then the PSU is faulty. Note if readings can be round off to the given values then the output is fine. cheers.

Outages are frequenly accompanied by power surges. It sounds like your power supply got cooked and does not produce enough power to start your computer anymore.

They are inexpensive and are easily replaced. Take a couple of digital pictures of it in your case and then remove it.
Measure the dimensions and go find an ATX power supply that will fit. I recommend that you go up to at least 350 watts. Use your pictures to help you install the new power supply.

Power supply light flashing green ,,, tried unplugging mother board still flashes green is it the power supply or the mother board?


Most computer testing facilities will test your current power supply for free. A replacement is very inexpensive to replace. Bestbuy, MicroCenter, small computer shops and buy replacemnent from Amazon.com, newegg.com.. Just make sure you have the correct information for your replacement. The model number on the power supply would be your best bet in most cases. Good luck and have a great day. I buy power supplies as low as $15 dollars Generic

My computer ps is not providing power to the mother board or any of the periphals. It is a Bestec ps the led on the back of the supply flashes very slowly. Any suggestions before I go out and replace it?


Disconnect the ATX main connector, bridge (with a wire clip) the green wire and any black (negative) wire, this should allow you to power up the PSU... now take a digital multimeter and measure the voltages on the 3.3v (orange), 5.0v (red) & 12v (yellow) lines, you will need to place the negative lead off the DMM on any black (negative) wire to achieve this...

If your PSU is off specification ie. more than 5% variance this IS your issue.

FWIW Don't waste your money on another Bestec PSU

When you say you have no power at all to your computer, have you checked the motherboard to see if you have a green light that comes on? You have to take the cover off and look at the motherboard. If the light does come on, it isn't your power supply. It is the motherboard. Good luck!

PC not booting


the mother board can have a short and the green light is on, replace the motherboard. when the power box goes bad, most of the time it shorts the mother board out, this has happened to me a few times. Farren
